Description

Technical Field

[0001] This utility model relates to the field of die-cutting equipment technology, specifically an adjustable multi-functional circular die cutter. Background Technology

[0002] Circular die-cutting equipment is a highly efficient and precise cutting device that uses the rotation of a circular blade to die-cut materials. This equipment is suitable for high-speed, high-precision cutting and is widely used in industries such as packaging, printing, shoemaking, and rubber. Circular die-cutting machines can cut various materials, such as paper, leather, fabric, and film, making them suitable for mass production and products with high precision requirements. In the packaging industry, circular die-cutting machines can cut various shapes of cardboard, paper, foam board, and other materials to make packaging boxes, paper bags, gift boxes, and other products. In the shoemaking industry, it can be used to cut leather, shoe materials, and other materials to make shoe soles, uppers, and other components. In the clothing industry, circular die-cutting machines can be used to cut fabrics to make clothing, shoes, and other products. In the printing industry, it can be used to cut various printed materials, such as labels and stickers.

[0003] A search revealed Chinese patent application CN202010165433.8, which discloses a satellite-type circular die-cutting machine, relating to the technical field of die-cutting machines. The machine includes a body and a mandrel. The body is provided with a mounting base for mounting the mandrel. It also includes a die-cutting structure for processing raw materials and a backing structure for laying multiple layers of material, arranged circumferentially along the mandrel; and a drive structure for driving the mandrel to rotate. This invention has the advantage of simultaneously realizing backing die-cutting and multi-blade nesting cutting processes.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-3 This utility model provides a technical solution:

[0027] An adjustable multi-functional circular knife machine includes:

[0028] Main structure; The main structure includes a U-shaped frame, a pressing roller 6 and a cutting roller 5 distributed vertically within the frame, and blades 10 distributed on the outer wall of the cutting roller 5. A motor 17 for driving the cutting roller 5 is installed on one side of the outer wall of the frame; The frame includes a base 1, a first support plate 2, a second support plate 3 and a third support plate 4. The first support plate 2 is located on one side of the base 1, the second support plate 3 is located on the other side of the base 1, and the third support plate 4 is located at the upper end of the second support plate 3;

[0029] It also includes an adjustment structure for adjusting the blade 10; the adjustment structure includes a positioning groove provided on the outer wall of the cutting roller 5 and a positioning seat 9 located at the lower end of the blade 10. The blade 10 is inserted into the inside of the positioning groove through the positioning seat 9 and is positioned by the locking screw 12. The positioning groove is distributed in multiple sets at equal intervals on the cutting roller 5.

[0030] One end of the positioning groove passes through one side of the cutting roller 5 and is connected to the outside. The positioning groove includes a lower groove 7 and an upper groove 8. The lower groove 7 is circular, and the positioning seat 9 is adapted to the lower groove 7. One end of the lower groove 7 has an internal thread 11, and the locking screw 12 is threadedly engaged with the internal thread 11, with the end of the locking screw 12 abutting against the end face of the positioning seat 9.

[0031] Specifically, the cutting roller 5 is rotatably installed between the first support plate 2 and the second support plate 3, and the cutting roller 5 is driven by the motor 17 on the outer wall of the first support plate 2. The pressing roller 6 is rotatably installed between the first support plate 2 and the third support plate 4.

[0032] By setting up a main structure including a frame, a pressure roller 6 and a cutting roller 5, the frame includes a base 1, a first support plate 2, a second support plate 3 and a third support plate 4, and an adjustment structure including a positioning groove and a positioning seat 9. The positioning seat 9 is located at the lower end of the blade 10. In actual use, the product to be processed is conveyed between the pressure roller 6 and the cutting roller 5. The motor 17 can be started to perform die cutting during the conveying process. Since multiple sets of positioning grooves are distributed around the cutting roller 5, and the positioning grooves are provided with internal threads 11, the number of blades 10 can be flexibly adjusted according to actual needs, and the spacing between adjacent blades 10 can be adjusted according to actual needs. The positioning seat 9 at the lower end of the blade 10 is inserted into the positioning groove, and the blade 10 protrudes through the upper groove 8 in the positioning groove. Then, the locking screw 12 is installed on the end with the positioning groove and the internal thread 11, and the end of the locking screw 12 abuts against the positioning seat 9 to position the blade 10.

[0033] To ensure the stability of the blade 10's positioning, the positioning seat 9 and the lower groove 7 of the positioning groove are matched, and the blade 10 and the upper groove 8 of the positioning groove are matched.

[0034] In summary, this device has a simple structure and is easy to use. Through the cooperation of the main structure and the adjustment structure, the number of die-cutting blades 10 and the spacing between adjacent blades 10 can be flexibly adjusted to adapt to different processing needs, greatly improving the flexibility and applicability of the equipment and making it highly practical.

[0035] In addition, please see Figure 4 :

[0036] The upper end of the first support plate 2 and the third support plate 4 are respectively provided with notches 13. Connecting rods 15 are symmetrically arranged in the notches 13, and bushings 14 are slidably sleeved on the connecting rods 15. The pressure roller 6 is rotatably installed between the two sets of bushings 14, and a compression spring 16 is sleeved on the connecting rod 15 between the bushings 14 and the inner top of the notch 13.

[0037] By connecting the shafts and bushings 14 at both ends of the pressure roller 6, and with the bushings 14 slidably installed in the notch 13 via the connecting rod 15, and the compression spring 16 sleeved on the connecting rod 15, the product can be firmly pressed against the cutting roller 5 during the product conveying process. In this way, when the cutting roller 5 is working, it can not only ensure the effectiveness of die cutting, but also increase the friction during the product conveying process, making it less prone to slippage and facilitating product processing.

[0038] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
